DOG-CART.-

SPECIFICATION forming part of Letters Patent No. 265,014, dated September 26, 1882.

.Application inea April ze, 1882. (No model.)

To all whom it may concern Be it known that I, EDWARD BowMAN, of Santa Cruz, in the county of Santa Cru?J and State of California, have invented a new and Improved Dog-Cart, of which the following is a full, clear, and exact description.

My invention relates to that class of vehicles known as dogcarts, and has for its object to prevent the motion of the animal from affecting the vibratory or rocking movement of the `vehicle body or box.

The inventioniconsistsin a dog-cart having its body supported byvtransverse crank-shafts provided in or pivotcd to the supportingsprings, and which box has one or more spiral or other springs attached to the front ot' the box and. to the shafts, whereby the box will be rocked or vibrated independently of the movements of the animal, and the box will not be jolted or shaken by the irregular movements ofthe animal.

Reference is to be had to the accompanying drawings, formingpart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure lis a longitudinal elevation of my improved dog-cart," showing it constructed with side springs. Fig. 2 is a plan view of the under side of the same. Fig. 3 is a detail longitudinal elevation of one ofthe crank-shafts.

Two transverse shafts or rods, A, provided with cranks B at the ends, are held to the under side of the vehicle body or box C by clips I) in such a manner that these shafts can turn-thatis, the box can swingen these crankallel with the box--can be used to supportthe box; but in this case the cranks of the shafts A may be journaled to these springs, sol that the box can rock or vibrate on thespring-bar. The front spring, H, cannot be dispensed with, as it prevents sudden lurchin g movements of the box.

In the dog-carts constructed heretofore the movements of the vehicle-box are governed by the movements of the horse, and these movements are very unpleasant for the occupant ot' the vehicle, which is jolted and shaken very irregularly. f

In my improved dog-cart the box is not supported directly by the springs, but the crankshafts A are interposed between the springs and the box, and give the box a rocking or vibrating movement forward and backward, and the irregular movement of the animal is counteracted by the springs and the crank-shafts. The spring H assists materially in giving the box the easy rocking or vibrating movement.

In place of the crank-shafts short arms or shackles can be used, which are pivoted to the side of the box and to the supporting-springs.

One or more front springs, H, may be used, as may be desired, or these springs can be attached tothe rear of the box and to rear extensions ot' the shafts. Also, in place of the crank-shafts cross-springs can be used with joints or shackles at the end ot'side and crosssprings in connection with spring H.

Having thus fully described my invention, I claim asnew and desire to secure by Letters Patent- The combination, in a dog-cart constructed as herein described, of the crank-shaped sup ports A,"side springs, E, and front spring, H, substantially as shown and specitied.
